3.0 JACK OPERATING INSTRUCTIONS

Place the jack on a firm foundation, capable of supporting the expected load. Make sure the jack base (1) is properly aligned perpendicular to the
load and that the base is fully supported. Also, be sure that the jack is properly supported at the lifting point (5) in a manner that the jack cannot slip
or the load cannot shift.
IMPORTANT: If additional attachments or other component are fixtured to the base (1) and/or head (4) locations, be certain that the jack
cannot slip or the load cannot shift; refer to the illustration for pipe dimension and fit.
Using a 22mm wrench on the hex section (3), apply torque to extend or retract the load screw (2). In some cases, where other attachments are
fixtured at the head or base, it may be necessary to restrain the base (1) of the jack using a 51mm wrench to make the screw extender retract.
